Non destructive testing

Non destructive testing is defined as testing and analysis techniques used to evaluate materials, components, structures or systems without causing damage. Some common non destructive testing methods are outlined in the document, including ultrasonic, radiographic, eddy current, and magnetic particle testing. Non destructive testing provides advantages like leaving the tested piece undamaged, being accurate and repeatable, and being economical by preventing unnecessary replacement of items. It has wide applications in industries like aerospace, marine, power, and petroleum pipelines to find flaws and defects without destroying the materials or components.
